下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的要素。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。
为了更好的理解本申请实施例公开的一种功率确定方法，下面首先对本申请实施例适用的通信系统进行描述。
请参见图1，图1为本申请实施例提供的一种通信系统的架构示意图。该通信系统可包括但不限于一个第一网络设备、一个第二网络设备和一个终端设备，图1所示的设备数量和形态仅用于举例并不构成对本申请实施例的限定，实际应用中可以包括两个或两个以上的网络设备和两个或两个以上的终端设备。图1所示的通信系统以包括一个网络设备101和一个终端设备102为例。
需要说明的是，本申请实施例的技术方案可以应用于各种通信系统。例如：长期演进(Long Term Evolution，LTE)系统、第五代移动通信系统、5G新空口系统，或者其他未来的新型移动通信系统等。
本申请实施例中的网络设备101是网络侧的一种用于发射或接收信号的实体。例如，网络设备101和可以为演进型基站(Evolved NodeB，eNB)、传输点(Transmission Reception Point，TRP)、NR系统中的下一代基站(Next Generation NodeB，gNB)、其他未来移动通信系统中的基站或无线保真(Wireless Fidelity，WiFi)系统中的接入节点等。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。本申请实施例提供的网络设备可以是由集中单元(Central Unit，CU)与分布式单元(Distributed Unit，DU)组成的，其中，CU也可以称为控制单元(Control Unit)，采用CU-DU的结构可以将网络设备，例如基站的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。
本申请实施例中的终端设备102是用户侧的一种用于接收或发射信号的实体，如手机。终端设备也可以称为终端设备(terminal)、用户设备(user equipment，UE)、移动台(Mobile Station，MS)、移动终端设备(Mobile Terminal，MT)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(Mobile Phone)、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端设备、增强现实(Augmented Reality，AR)终端设备、工业控制(Industrial Control)中的无线终端设备、无人驾驶(Self-Driving)中的无线终端设备、远程手术(Remote Medical Surgery)中的无线终端设备、智能电网(Smart Grid)中的无线终端设备、运输安全(Transportation Safety)中的无线终 端设备、智慧城市(Smart City)中的无线终端设备、智慧家庭(Smart Home)中的无线终端设备等等。本申请的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
在LTE或者5G NR系统中，终端设备102为了满足带内和带外辐射的要求，允许进行一定的功率回退，即MPR(maximum power reduction，最大功率回退)。MPR定义了针对所有调制方式和分配的资源块数量的特定组合下最大功率等级的允许降低量。功率回退的大小对于终端设备102允许的最大功率配置会造成一定的影响。功率回退越大，则终端设备102允许的功率也会越小，从而对终端设备102的上行覆盖造成一定的影响。
终端设备102的功率回退主要取决于带内和带外的辐射要求，带外的辐射要求主要取决于法规的要求。但是在一些特殊的情况下，比如在一些特殊的如公海，沙漠，高山等人迹罕至的地方，法规要求的功率回退可能导致终端设备102的覆盖减少，进而影响终端设备102的通信质量。
因此，在某些特殊情况下，比如在一些特殊的如公海，沙漠，高山等人迹罕至的地方，终端设备102带外辐射的限制可以不需要遵从一般情况下的带外辐射要求，对其带外辐射的限制可以放宽，从而在某一些条件下，减小不必要的功率回退，这样能够有利于增加终端设备102的上行覆盖，提高通信效率和通信质量。
本申请的实施例中，通过确定所述终端设备的带外发射限制信息，根据该带外发射限制信息，确定终端设备的功率，使得终端设备能够根据带外发射的不同限制，确定不同的功率，根据不同的情况确定不同的功率回退值，能够在一些特殊情况下，减小不必要的功率回退，增加终端的上行覆盖，有效提高了通信的效率和通信链路的质量。
可以理解的是，本申请实施例描述的通信系统是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
下面结合附图对本申请所提供的功率确定方法及其装置进行详细地介绍。
请参见图2，图2是本申请实施例提供的一种功率确定方法的流程示意图。需要说明的是，本申请实施例的功率确定方法由终端设备执行。如图2所示，该方法可以包括如下步骤：
步骤201，确定所述终端设备的带外发射限制信息。
其中，带外发射限制信息是指，对终端设备的带外发射进行限制的信息，也就是对终端设备的带外发射的要求。
终端设备在进行信号发射时，由于内部元器件是非理想条件下的器件，存在或多或少的非线性，在信号调制、发射的过程中，会产生一些非规定频率范围内的信号，也就是超过必要带宽的一个或多个频率的发射。这样，在一个通信系统内，一个终端设备的带外发射可能会对系统内的其他设备的通信造成干扰，因此，一般对终端设备的带外发射会有限制和要求。
在一些实施方式中，带外发射限制信息包括：邻道泄漏比ACLR(Adjacent Channel Leakage Ratio)，带外辐射(out of band emission)和带外杂散辐射(spurious emission)中的至少一种。
其中，邻道泄漏比ACLR是以指定信道频率为中心的滤波平均功率与以相邻信道频率为中心的滤波平均功率之比。
可选地，带外发射限制信息是根据终端设备所在的服务小区的部署地的地理特征或者相关法规要求 来确定的。
可以理解的是，带外发射限制信息可以是邻道泄漏比ACLR的下限数值，带外辐射的上限数值和带外杂散辐射的上限数值中的至少一种，也就是表示限制邻道泄漏比ACLR，带外辐射和带外杂散辐射中的至少一种不能超过该限制。
在一些实施方式中，终端设备接收网络设备发送的指示信息，并根据该指示信息，确定终端设备的带外发射限制信息。
也就是，网络设备根据自身部署地的地理特征或者相关的法规要求，向终端设备发送指示信息，来指示终端设备的带外发射限制信息。
可选地，该指示信息至少为1bit。
在一些实施方式中，终端设备确定自身位置信息，并根据该位置信息，确定终端设备的带外发射限制信息。
步骤202，根据该带外发射限制信息，确定终端设备的功率。
终端设备在确定了带外发射限制信息之后，会根据该带外发射限制信息，确定自身的功率。
可选地，终端设备根据该带外发射限制信息，确定终端设备的功率回退值，再根据该功率回退值，确定终端设备的功率。
在一些实施方式中，终端设备根据带外发射限制信息、终端设备的时频资源位置，资源块数和终端设备的调制方式，确定功率回退值。
在一些实施方式中，终端设备根据带外发射限制信息，确定功率偏移值，根据终端设备的时频资源位置，资源块数和终端设备的调制方式，确定参考功率回退值，再根据参考功率回退值和功率偏移值，确定功率回退值。
其中，终端设备的时频资源位置是指，终端设备分配的时频资源在传输带宽配置中的位置，一般分为内部(inner)时频资源分配(allocation)，外部(outer)时频资源分配以及边缘(edge)时频资源分配，内部时频资源分配还可以分为区域(region)1和区域2。
可以理解的是，在不同的应用场景下，对时频资源位置的定义可以是不同的，也就是对何种时频资源分配属于内部时频资源分配，何种时频资源分配属于外部时频资源分配，以及何种时频资源分配属于边缘时频资源分配的定义可以是不同的。
可选地，本申请实施例中的时频资源为资源块RB(Resource Block)。
在本申请实施例中，终端设备在确定了自己的功率之后，还可以将确定的功率发送给网络设备，以使网络设备根据该功率向终端设备配置功率。
综上，通过确定所述终端设备的带外发射限制信息，根据该带外发射限制信息，确定终端设备的功率，使得终端设备能够根据带外发射的不同限制，确定不同的功率，根据不同的情况确定不同的功率回退值，能够在一些特殊情况下，减小不必要的功率回退，增加终端的上行覆盖，有效提高了通信的效率和通信链路的质量。
请参见图3，图3是本申请实施例提供的一种功率确定方法的流程示意图。需要说明的是，本申请实施例的功率确定方法由终端设备执行。如图3所示，该方法可以包括如下步骤：
步骤301，接收网络设备发送的指示信息。
其中，该指示信息是网络设备发送给终端设备的，用于确定终端设备的带外发射限制信息。
网络设备根据自身部署地的地理特征或者相关的法规要求，确定终端设备的带外发射限制信息，通过该指示信息，指示终端设备确定带外发射限制信息。
其中，可选地，带外发射限制信息包括：邻道泄露比ACLR，带外辐射和带外杂散辐射中的至少一种。
在一些实施方式中，网络设备发送的指示信息为1bit，该指示信息用来指示终端设备是否可以放松对带外发射的限制。
可选地，可以该指示信息为0时指示可以放松，指示信息为1时指示不可以放松，或者该指示信息为1时指示可以放松，指示信息为0时指示不可以放松。
可以理解的是，终端设备在接收到指示可以放松对带外发射的限制的指示信息之后，可以直接确定对带外发射的限制的放松程度的默认值，其中可以根据环境需求等等的不同设置不同放松程度的默认值。
在一些实施方式中，网络设备发送的指示信息为多个bit，该指示信息能够指示终端设备对带外发射的限制的放松程度。
比如，指示信息为2bit，指示信息00,01,10,11分别对应不同的放松程度。
可选地，放松程度与带外发射限制信息与标准参考值之间的变化量，或者该变化量为标准参考值的设定比例相关。
可以理解的是，可以根据环境需求等等的不同对指示信息以及指示信息所对应的放松程度进行不同的设置。
